Take a facts-based journey through the cosmos and discover how we know what we know. With hosts Fraser Cain and Dr. Pamela Gay. Recorded live on YouTube.
Happy #Podcast day, everyone!
It is arguable that humanity now has the technological ability to live on Mars. It would be done at enormous expense & sacrifice, and there are some tricky problems we haven’t solved yet. Although we could live on Mars, should we?
Now out wherever you get podcasts.

Info on our server woes. We were dying beneath bots & scrapers, so we turned on free Cloudflare. That helped, but we were still getting hammered by ... China. In the mix of regular reboots, our database decided it was just done (same, really), & wouldn't come back after a force stop.
